#
# Find Perl libraries
#
# This module finds if PERL is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
# ::
#
# PERLLIBS_FOUND = True if perl.h & libperl were found
# PERL_INCLUDE_PATH = path to where perl.h is found
# PERL_LIBRARY = path to libperl
# PERL_EXECUTABLE = full path to the perl binary
#
#
#
# The minimum required version of Perl can be specified using the
# standard syntax, e.g. find_package(PerlLibs 6.0)
#
# ::
#
# The following variables are also available if needed
# (introduced after CMake 2.6.4)
#
#
#
# ::
#
# PERL_SITESEARCH = path to the sitesearch install dir
# PERL_SITELIB = path to the sitelib install directory
# PERL_VENDORARCH = path to the vendor arch install directory
# PERL_VENDORLIB = path to the vendor lib install directory
# PERL_ARCHLIB = path to the arch lib install directory
# PERL_PRIVLIB = path to the priv lib install directory
# PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
# find the perl executable
